4 seasons tires should not have been invented. And now that they exist, they 
should be banned.
I live in Quebec, and most of the ground is clay, so salt make our ground more 
stable. We also have varieties of grass that are more resistant to salt 
contamination. Even if we use TONS of salt each winters, there is only little 
apparent effect on most of the vegetation. At times, the streets are a sparkling 
white from all that salt dust... and with the wind picking that dust...
